Closes FMG-2 Upgrades Go and every dependency to their latest revisions, and removes the `gotoolkit` dependency in favour of the standard library and the libraries it was wrapping. Supersedes #7 — identical tree, recreated under the `butterrobot` account. ## gotoolkit removal - **`encoding.NewTOMLEncoding()`** — a thin wrapper over `pelletier/go-toml/v2`. Now used directly, behind a new `smtp2shoutrrr.LoadConfig(path)` shared by both commands. Previously both `cmd/smtp2shoutrrr` and `cmd/sendmail` duplicated the open/decode/`SetDefaults` sequence, and neither closed the config file. - **`model.Server`** — a three-method interface with a single implementation. `NewSMTPServer` now returns a concrete `*Server`, and the unused `IsEnabled()` is gone. - **`service.NewService(...).Start()/WaitStop()`** — replaced by `signal.NotifyContext` in `main`. `Server.Start(ctx)` now owns its own lifecycle: it serves until the context is cancelled, then calls `Shutdown` with a 10s deadline. Behaviour matches the old service, without the indirection. ## Version bumps | | from | to | |---|---|---| | Go | 1.25.6 | 1.27.1 | | `emersion/go-smtp` | 0.24.0 | 0.25.0 | | `stretchr/testify` | 1.9.0 | 1.12.1 | | `pelletier/go-toml/v2` | 2.2.3 (indirect) | 2.4.3 (direct) | | `x/crypto/x509roots/fallback` | 2025-02-14 | 2026-09-02 | | alpine (Containerfile) | 3.20 | 3.24 | | golangci-lint | v2.8.0 | v2.13.2 | | `actions/checkout`, `actions/setup-go` | v6 | v7 | Indirects also refreshed (`x/net` 0.25.0 → 0.58.0, `x/sys`, `x/tools`, `fatih/color`, `go-cmp`, `logr`). `containrrr/shoutrrr` and `emersion/go-sasl` were already at their latest published revisions. ## Dropping `goreleaser-action` Bumping `actions/goreleaser-action` v6.4.0 → v7.2.3 broke the `goreleaser-lint` job: v7.1.0 made cosign signature verification of the action's own goreleaser download mandatory, and `ci-base` ships no cosign. Rather than pin the action back, this drops it. `ci-base` already installs goreleaser from the upstream apt repo — that is what `make build` has always used — so the action was downloading a second copy of a tool the image already had. Both workflows now invoke it directly, and `goreleaser check` moves behind a `make check` target, so every CI job runs a make target like the rest of the pipeline. ## Tests Coverage 63.1% → 75.9%. New tests cover `LoadConfig` (parsing, defaults, missing file, invalid TOML) and the replacement lifecycle — that a cancelled context shuts the server down and releases the listener, and that a bind failure propagates out of `Start`. On this exact tree (as PR #7) CI passed `format`, `lint`, `test` and `goreleaser-lint`. Locally, against Go 1.27.1: `make format` (clean diff), `make check`, `make ci-lint` (0 issues), `make test`, `make build` (6 targets). The release binary was also smoke-tested end to end: mail accepted, forwarded to a shoutrrr generic target, and `SIGTERM` shut it down cleanly with exit 0. Note: `release.yml` only runs on tags, so its goreleaser step is not exercised by this PR. The env vars it depends on (`GITEA_TOKEN`, `GORELEASER_FORCE_TOKEN`) are read by goreleaser itself rather than by the action, so invoking the binary directly is equivalent. ## Also Removed the unused `ANONYMOUS` SASL client from `cmd/sendmail` — its only caller was a commented-out line, and it was the last thing pulling `go-sasl` into that command.
